Question

我需要编写Spring Component Bean，并且需要从常规类（来自abc.jar）扩展。

@Component
public DefClass extends AbcClass{
..
}

这是抛出错误AbcClass是一个非Spring类，不知道如何创建它作为SpringBean。我试着在我的application-Context.xml中定义

<bean id ="abcBean" class ="package.AbcClass" "/>
        <bean id ="defClass"  class ="package.defClass" parent="abcBean"/> 

WEB-INF/classes/applicationCotext.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: com.tivoli.pd.jutil.PDException

Answer 1

这不是春季项目。该类不可用（猜测abc.jar未添加到类路径中）。检查如何构建应用程序，检查abc.jar是否存在并包含在类路径中。

从非Spring类扩展Spring类
